Alfvén waves in the magnetosphere generated by shock wave/plasmapause interaction
We study Alfvén waves generated in the magnetosphere during the passage of an interplanetary shock wave. After shock wave passage, the oscillations with typical Alfvén wave dispersion have been detected in spacecraft observations inside the magnetosphere.

New plasmapause model derived from CHAMP field-aligned current signatures [PDF]
We introduce a new model for the plasmapause location in the equatorial plane. The determination of the L-shell bounding the plasmasphere is based on magnetic field observations made by the CHAMP satellite in the topside ionosphere.

Plasmapause, Convection, and Reconnection [PDF]
AbstractBeing one of the first generation of space scientists who entered this field right after the space became accessible to in situ observations, I had good luck of addressing some of the basic questions in this field from the early years of my carrier. These are development of global convection in the magnetosphere when the interplanetary magnetic

AbstractRecent studies based on CLUSTER, CRRES, and especially on THEMIS satellite data have revealed the statistical behavior of the global plasmapause such as eastward azimuthal plasmapause propagation and radial plasmapause motion between 21 and 07 magnetic local times (MLTs) most likely at postmidnight.

Saturn's Plasmapause: Signature of Magnetospheric Dynamics [PDF]
AbstractWe explore the paradigm that Saturn's plasmapause marks the boundary between the magnetic flux tubes that have been circulating around the planet for some time, accumulating a dense load of Enceladus‐sourced material, and those that have recently undergone tail reconnection, shedding the bulk of the cold plasma and retaining a more tenuous ...

An auroral westward flow channel (AWFC) and its relationship to field-aligned current, ring current, and plasmapause location determined using multiple spacecraft observations [PDF]
An auroral westward flow channel (AWFC) is a latitudinally narrow channel of unstable F-region plasma with intense westward drift in the dusk-to-midnight sector ionosphere. AWFCs tend to overlap the equatorward edge of the auroral oval, and their life

A machine-learning-based electron density (MLED) model in the inner magnetosphere
Plasma density is an important factor in determining wave-particle interactions in the magnetosphere. We develop a machine-learning-based electron density (MLED) model in the inner magnetosphere using electron density data from Van Allen Probes between ...

The Evolution of Whistler Hiss‐Like Waves Across Plasmapause: Hiss to Exohiss
The exohiss waves are hiss‐like whistler mode waves that occur outside plasmapause. Although these waves can cause the loss of radiation belt electrons ∼

Polar observations of electron density distribution in the Earth’s magnetosphere. 2. Density profiles [PDF]
Using spacecraft potential measurements of the Polar electric field experiment, we investigate electron density variations of key plasma regions within the magnetosphere, including the polar cap, cusp, trough, plasmapause, and auroral zone.
